watermarks-remover is an open-source Python service and agent skill that removes multi-vendor AI provenance marks from text and files you own. It targets three layers: invisible Unicode characters and exotic whitespace, statistical token-sampling text watermarks from vendors like Claude, Gemini SynthID-Text, and OpenAI, and C2PA or EXIF metadata embedded in PNG, JPEG, SVG, PDF, DOCX, HTML, and other formats. The tool runs as a lightweight local HTTP service using Python 3.10+ stdlib with no external dependencies, and exposes an OpenAPI-documented REST interface for integration with agents or web apps. Docker images and agent skill integrations for Grok and Cursor are also provided.
